Description

Technical Field

[0001] This utility model belongs to the field of water pump heat dissipation technology, specifically a water pump casing heat dissipation structure and a water pump. Background Technology

[0002] During operation, water pumps generate a significant amount of heat due to motor operation and friction during liquid transport. If this heat cannot be dissipated in time, it will cause the pump casing temperature to become too high, thus affecting the pump's performance and lifespan. For example, excessively high pump casing temperatures may accelerate the aging of internal seals, leading to decreased sealing performance and leaks. Furthermore, excessively high temperatures may also affect the motor's insulation performance, increasing the risk of motor failure.

[0003] Currently, existing heat dissipation methods for water pump casings have significant shortcomings. Common finned structures rely solely on increasing the heat dissipation area, which is severely inefficient when dealing with the large amounts of heat generated by high-power water pumps. While active cooling methods such as air cooling and water cooling can improve heat dissipation to some extent, air cooling is susceptible to environmental dust and debris, leading to blockages in the heat dissipation channels and a decrease in cooling efficiency over time. Furthermore, components such as fans are prone to failure. Water cooling methods suffer from complex structures, high installation and maintenance costs, and leaks and blockages in the cooling water pipes, making repairs difficult and severely impacting the normal operation of the water pump. Therefore, a new heat dissipation structure is urgently needed to solve these problems. Utility Model Content

[0004] To overcome the technical defects of the existing technology, this utility model provides a water pump casing heat dissipation structure and a water pump.

[0005] The technical solution adopted by this utility model is: a water pump casing heat dissipation structure, including a pump casing body and a mounting cover plate. The mounting cover plate is installed at the end of the pump casing body. A spiral groove is opened on the surface of the pump casing body. A cooling water pipe is wound around the surface of the pump casing body through the spiral groove. Five heat-conducting copper strips are provided on the surface of the cooling water pipe. Each heat-conducting copper strip is connected to the pump casing body by a first bolt.

[0006] By adopting the above technical solution, the heat dissipation structure includes a pump casing body and a mounting cover. The mounting cover is installed at the end of the pump casing body. A spiral groove is formed on the surface of the pump casing body, and a cooling water pipe is wound around the spiral groove. This design greatly increases the contact area and contact path between the cooling water pipe and the pump casing body, allowing the cooling water pipe to more effectively remove the heat generated by the pump casing body during water circulation, achieving efficient water cooling. Five heat-conducting copper strips are set on the surface of the cooling water pipe, and each heat-conducting copper strip is connected to the pump casing body by a first bolt. The heat-conducting copper strips utilize their excellent thermal conductivity to quickly conduct heat from the pump casing body to the cooling water pipe, further improving heat transfer efficiency. The first bolt connection ensures the stability of the connection between the heat-conducting copper strip and the pump casing body, facilitating subsequent installation, maintenance, and replacement.

[0007] Preferably, the cooling water pipe is equipped with an inlet pipe and an outlet pipe at both ends.

[0008] By adopting the above technical solution, an inlet pipe and an outlet pipe are installed at both ends of the cooling water pipe. The inlet pipe is used to connect to the inlet of the external water circulation system, so that cooling water can flow into the cooling water pipe. The outlet pipe is connected to the outlet of the water circulation system, so as to discharge the cooling water after absorbing heat, thereby forming a complete water circulation heat dissipation loop, ensuring the continuous circulation of cooling water in the cooling water pipe, and providing a guarantee for stable heat dissipation.

[0009] Preferably, each of the heat-conducting copper strips has a groove on its surface that is compatible with the cooling water pipe, and the cooling water pipe is in contact with the surface of the heat-conducting copper strip through the groove.

[0010] By adopting the above technical solution, a novel utility model is designed with grooves on the surface of each heat-conducting copper strip that are adapted to the cooling water pipe. The cooling water pipe is embedded in the grooves and fits snugly against the surface of the heat-conducting copper strip. This structural design significantly increases the contact area between the two. The larger contact area allows the heat transferred from the pump casing to the heat-conducting copper strip to the cooling water in the cooling water pipe more efficiently, reducing heat loss during the heat transfer process, further optimizing heat conduction efficiency, and improving the water cooling effect.

[0011] Preferably, the surface of the heat-conducting copper strip is covered with a plurality of heat-dissipating copper fins.

[0012] By adopting the above technical solution, heat dissipation copper fins are fitted onto the surface of the heat-conducting copper strips, increasing the heat dissipation area of ​​the heat dissipation structure. When the heat from the pump casing is conducted to the heat-conducting copper strips, the heat dissipation copper fins absorb the heat and dissipate it into the environment through convection heat exchange with the surrounding air. More heat dissipation copper fins mean a larger heat dissipation area, thereby enhancing the natural heat dissipation capacity of the entire heat dissipation structure, assisting water cooling, and further reducing the pump casing temperature.

[0013] Preferably, the inner side of the heat dissipation copper sheet is provided with a limiting groove that is adapted to the heat-conducting copper strip.

[0014] By adopting the above technical solution, the utility model of opening a limiting groove on the inner side of the heat dissipation copper fin that matches the heat-conducting copper strip, when the heat dissipation copper fin is sleeved on the heat-conducting copper strip, the heat-conducting copper strip is embedded in the limiting groove. This structure restricts the movement of the heat dissipation copper fin on the heat-conducting copper strip, ensuring that the heat dissipation copper fin maintains a stable installation position during the operation of the water pump and will not shift due to vibration or other factors, thereby ensuring that the heat dissipation copper fin can continuously and stably perform its heat dissipation function.

[0015] Preferably, a circular hole is provided on the inner side of the heat sink copper sheet, and a connecting rod is provided in the circular hole. The connecting rod is connected to the heat sink copper sheet through the circular hole.

[0016] By adopting the above technical solution, a circular hole is opened on the inner side of the heat sink copper fin, and a connecting rod passes through the circular hole to connect with the heat sink copper fin. The connecting rod not only serves to connect multiple heat sink copper fins, making the heat sink copper fins form a relatively orderly overall structure, but also provides a supporting foundation for the subsequent installation of the cooling fan. Through this connection method, the heat sink copper fin utility model, the connecting rod, and subsequent cooling fan and other components are organically combined to form a complete heat dissipation system.

[0017] Preferably, one end of the connecting rod is connected to the mounting cover plate by a second bolt, and the other end of the connecting rod is fixedly connected to a mounting ring, with a cooling fan installed on the inner side of the mounting ring.

[0018] By adopting the above technical solution, one end of the connecting rod is connected to the mounting cover plate via a second bolt, ensuring a stable installation of the connecting rod on the water pump; the other end of the connecting rod is fixedly connected to the mounting ring, and the cooling fan is installed inside the mounting ring. When the cooling fan is activated, it accelerates airflow and quickly removes heat from the surface of the heat sink copper fins, achieving air cooling. The combination of air cooling and water cooling significantly improves the heat dissipation efficiency of the entire water pump casing heat dissipation structure, enabling the water pump to maintain a suitable operating temperature during operation.

[0019] A water pump includes a water pump vibration damping mounting structure and a pump body. A mounting base is fixedly connected to the surface of the pump body, and the mounting base is mounted on the surface of a fixing plate by bolts.

[0020] By adopting the above technical solution, the entire water pump includes a water pump casing heat dissipation structure, a mounting bracket, an impeller protective shell, and a water pump body. The water pump body is installed inside the pump casing and is the core component for realizing the liquid transportation function of the water pump; the mounting bracket is installed on the surface of the mounting cover plate and serves to support and fix the impeller protective shell; the impeller protective shell is installed on the outside of the impeller in the water pump body through the mounting bracket, protecting the impeller and preventing foreign objects from entering and affecting the normal operation of the impeller.

[0021] The beneficial effects of this utility model are: water cooling is achieved by spiral groove winding of cooling water pipes, and in conjunction with heat-conducting copper strips, heat dissipation copper fins and cooling fans, a heat dissipation method combining water cooling and air cooling is formed. Multiple heat dissipation methods work together to significantly improve heat dissipation efficiency and effectively solve the heat dissipation problem of high-power water pumps.

[0022] The heat-conducting copper strip is connected to the pump housing body by the first bolt, the heat dissipation copper fin is matched with the heat-conducting copper strip through the limiting groove, and the connecting rod is connected to the mounting cover plate by the second bolt. The connection of each component is stable, ensuring the stability of the entire heat dissipation structure during the operation of the water pump.

[0023] By employing detachable methods such as bolted connections, it is easy to inspect and replace individual components when the heat dissipation structure fails, thereby reducing maintenance costs and difficulty. Attached Figure Description

The cooling water in the cooling water pipe 24 circulates and carries away the heat, realizing water cooling heat dissipation. At the same time, the heat dissipation copper fins 27 absorb the heat from the pump casing 2 and the heat-conducting copper strips 22.

The other end is fitted with a mounting ring 282, and a cooling fan 283 is fixedly installed inside the mounting ring 282. Then, an inlet pipe head 25 and an outlet pipe head 26 are installed at both ends of the cooling water pipe 24, connecting to the external water circulation system.
